TIRE-HEATER.

SPECIFICATION forming part of Letters Patent No. 617,152, dated January 3, 1899.

Application filed January 5 l 8 9 8.

To all whom, t may concern.:

Be it known that we, EDWARD G. FERGU- soN and JOHN P. IIOLMEN, of Kensett, in the county of Vorth and State of Iowa, have invented a new and Improved Tire-Heater, of which the following is a full, clear, and exact description.

Our invention relates to improvements in devices used for heating tires to expand them before placing them upon a vehicle-wheel.

Our invention consists of the novel features hereinafter described and claimed.

The front of the heater is provided with doors, through which the tires may be readily inserted and removed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both figures.

Figure 1 is a front elevation of our device, the open position of the doors being shown by dotted lines; and Fig. 2 is a central sectional elevation taken from front to rear.

The object of our invention is to provide a convenient device which may receive a number of tires and quickly and evenly heat them by the expenditure of a small amount of fuel.

The heater consists of ythe annular chainber A, formed of metal and provided with doors B, pivoted at B' and adapted to be swung to one side, so as to open the entire front of the annular chamber. The central opening A' in the doors may be omitted, if desired; but the construction shown is that preferred.

A base A2 is attached to the bottom of the annular chamber A and serves as a furnace or receptacle for the fuel. This base is provided with a grate G and a draft-door C. A bar K is extended across the center of the back of the chamber and supports an arm J, which extends forward and is notched, so as to engage and hold the bars b, pivoted to the doors B and secured thereto by a staple or guide b. By raising the central ends of the bars b the doors B may be swung open.

The upper portion of the chamber has a series of pins or rollers E, supported from the rear and extending across the chamber. These pins or rollers are located one above the other and extend through the rear wall of the chamber, having their outer ends supserai No. 665,612. No man.)

part of the chamber is also provided with a,

chimney D, by which the products of combustion may b e discharged.

In using the device a fire is kindled upon the grate G, and the tires which are to be heated are placed upon the pins or rollers E. Each pin or roller may be of such length as to support several tires. The smaller tires will of course be placed upon the lower pins or rollers and the larger tires upon the upper ones. The device will consequently accommodate quite a number of tires at one time. Being entirely closed and with a portion thereof in close contact with the tire, the tires will be quickly and evenly heated. The crank I should of course be kept revolving most of thetime while the tires are being heated.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patentl.. A tire-heater, comprising an annular heating-chamber provided with means for heating it, and doors for opening and closing the front face thereof ,a central vertical framebar attached to the back, a bracket bar or bars secured to the frame-bar with its body parallel therewith and extending across the upper portion of the annular chamber, tiresupporting pins or rollers journaled in the frame and bracket bars and extending across the heating chamber, intermeshing gears upon said pins or rollers between the frame and bracket bars, one of the pins having a crank thereon.

2. A tire-heater, comprising an annular heating-chamber, provided with means for heating it and doors for opening and closing the front face thereof, a fixed arm having an upwardly-extending hook within the central opening in the heating-chamber and in line with the front face of the doors, guides upon the face of each door near its inner edge, and a bar pivoted to the face of each door near its outer edge and passing over its guide, the

free end thereof being adapted to swing down so as to engage the hook on the arm within the central opening in the chamber.

3. A tire-heater, comprising an annular heating-chamber provided with ineans for heating it and doors for opening and closing the front face thereof,a central vertical framebar attached to the back, a bracket bar or arm secured to the outer side of the framebar with its body parallel therewith and extending across the upper portion of the annular chamber, tire-supporting pins or rollers journaled in the frame and bracket bars and extending across the heating-chamber, intermeshing gears upon said pins or rollers between the frame and bracket bars, one of
